Title: Reference voltage circuit
Inventor: KURAISHI YOSHIAKI
IPC: H03F1/26
Filed: 1983-06-21
Abstract: PURPOSE:To obtain a reference voltage subject to temperature compensation and without fluctuation by the temperature by detecting an offset voltage of an operation amplifier in the 1st state so as to store the voltage and shifting this voltage by a charging voltage of the capacitor in the 2nd srate. CONSTITUTION:Switches S1-S3 are closed in the 1st state and the gain of the operation amplifier A1 becomes the unity. In taking an offset voltage of the operational amplifier A1 as VOS and a voltage applied to a non-inverting input as VB, a voltage VB+VOS appears at an output of the amplifier A1. Further, a voltage of VOS-VBE2 (VBE; base-emitter voltage of a transistor Q2) is charged in the 1st capacitor C1 and a voltage of -VBE2 is charged in the 2nd capacitor C2. Since the common mode shift voltage -VBE2 is cancelled by the operational amplifier A1 while being shifted by the charging voltage of the capacitors C1, C2 and does not appear at the output in the 2nd state where the 1st-3rd switches S1-S3 are opened, the offset voltage of the operational amplifier A1 is compensated by the shift voltage VOS and an accurate reference voltage is outputted.

Title: Production of surface-modified expandable resin particle
Inventor: HIRATSUKA YUJI
IPC: C08J9/22
Filed: 1987-05-06
Abstract: PURPOSE:To obtain expandable resin particles which can give a foam maintaining improved performance for a long time and having uniform cells, by suspending expandable resin particles and a modifying agent in water as a medium and applying a specified pressure to this system at a specified temperature. CONSTITUTION:Expandable resin particles are impregnated with a modifying agent in an aqueous suspension in a temperature range of the melting temperature of the expandable resin particles + or -20 deg.C and a pressure range of 0.1-20kg/ cm<2>G. As said expandable resin particles, particles of a polyolefin resin and/or a crosslinked polyolefin resin are usually used. Although any modifier may be used as said modifier so far as it can be dispersed in water with or without the aid of an emulsifier, those having melting temperatures lower than those of the expandable resin particles and being difficultly soluble in water are desirable. Examples of such modifiers include additive-type flame retardants (e.g., phosphate ester) and antistatic agents (e.g., polyoxyethylenealkylamine).

Title: Semiconductor laser
Inventor: SAKUMA ISAMU
IPC: H01S5/227
Filed: 1980-08-13
Abstract: PURPOSE:To simply obtain a laser light having narrow emitting angle from a semiconductor laser by forming a clad layer between an active layer and a light guide layer, thereby increasing the thickness of the light guide layer. CONSTITUTION:Positive is applied to an electrode 18, negative is applied to an electrode 19, and carrier is injected to an active layer 14. The layer 14 is interposed between clad layers 13, 15, 16 having sufficiently large forbidden band width on the outer periphery. Accordingly, the difference of the forbidden band widths can prevent the diffusion of the injected carrier to the clad layer side, thereby confining the carrier. Since the layer 12 is sufficiently thin, the laser light can be absorbed into the layer 12. A light waveguide is formed by the effective refractive index difference formed laterally of the layer 13, thereby stabilizing the lateral mode.

Filed: 1988-05-10
Abstract: PURPOSE:To match an image shown on a display device with colors by providing a gradation processing means which subjects the input image data of N bits to gradation processing using a MXM gradation matrix which establishes a specific relationship. CONSTITUTION:Input image data of analog signal is converted to an input image of N-bit digital signal (in this case, 4 bits are used) using an analog/ digital conversion means 3, and this input image is stored in an image memory 4. Then the input image data of digital signal is subjected to gradation processing by a simulated gradation processing circuit 6 using the dither method. That is, the gradation level of each pixel of the input image data is compared with the threshold value of each appropriate pixel for the 8X8 dither matrix 7A, per the 8X8 matrix. If the gradation level is higher or equal, any appropriate pixel for output image data is accepted as a recording pixel. Consequently, the gradation level of each pixel of the output image data can be freely set by subdividing it. Then the data from the circuit 6 is output from an output terminal 8.
